There are several examples of evidence that support endosymbiosis theory. Mitochondria and chloroplasts contain their own small supply of DNA, which may be remnants of the genome the organelles had when they were independent aerobic bacteria.

JACKSON -- A 5-foot, 10-inch baby giraffe named Mika was born at Six Flags Great Adventure earlier this month, becoming the ninth giraffe in the park's Safari Off Road Adventure, park officials said Tuesday.
According to the San Diego Zoo, giraffes usually have only one baby at a time. In rare cases, they might have two. In December 2012, twin giraffes were born in a Chinese Zoo in the city of Shijiazhuang. The event was considered such a rarity for the species that it made the news all over the world.
